Hi @EthanSuero and @Audrey Ace Studio 👋
I did some checking and it seems there isn’t currently the abillity to specify a single or multiple locales when creating new items in Webflow. We’ve got a feature request open for the ability to set the locale so I’ve added your votes to that which will help to increase it’s priority. I can’t make any promises around when/if it will be added by but we’ll be sure to email you as soon as it is.
As a workaround, perhaps you could try using Webflow’s API Request action to create the item and specify the locales? It looks as though their Create Collection Items endpoint would be the one you’d want to use as it allows for items in a CMS Collection to be created across multiple locales. It’s a bit more of an advanced action since you’d need to reference Webflow’s API documentation but we have a generic guide on how to use API Request actions which you might find useful: Set up an API request action
Hope that helps. If you get stuck on setting that up or if there's anything else we can help with do let us know! 🙂
